Answer:
1. 240+180=420 packages.
2. 420 ÷ 240=2 toys and 1 left over.
3. 420 ÷ 180=2 books and 1 left over.
Step-by-step explanation:
Lilian can either put 1 toy and 1 book in the same package or separate them.
The initial expression is:
2x + 4(x - 2)
Replacing x by 3, we get:
2(3) + 4(3 - 2)
6 + 4(1)
6 + 4
10
The value of the expression is 10

Answer:
Step-by-step explanation:
Sum of angles in a Δ= 180°
x + 2x +3x = 180
6x= 180
Divide both sides by 6
x=30
sooo x= 1×30= 30, 2x= 2×30= 60, 3x=3×30= 90
since 30+60+90= 180
∴the angles are 30°,60° and 90° respectively
